Thanks for the response. That's the thing, all of that work is already done. Anyway, shortly after posting I think I found my solution (although I'm not out of the woods yet).
I need to handle the RowEditing event and inside of that event I have to do things in this order.
GridViewIngredient.EditIndex = e.NewEditIndex
PopulateIngredientGrid(DropDownListSource.SelectedValue)
Where PopulateIngredientGrid() builds the EntityCollection and then calls GridViewIngredient.DataBind()

Yes, is possible, but you have to do more work in opposite to use a LLBLGenProDataSource2.
If you use EntityCollections, you need to add logic to Fetch (at Page_Load?) and Persist to DB (catch GridView's events and put logic there to persist changes to DB, or add a global button to save everything).
